METHOD FOR SURGICAL TREATMENT OF LARGE JOINT PERIPROSTHETIC INFECTION USING POLYVALENT FAGODERM BACTERIOPHAGE Russian patent published in 2017 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: access is performed to the site of inflammatory complications. Modified necrotic tissue are cut removing abnormal soft tissues, including those from the metal endoprosthesis cavity, exposing the metal endoprosthesis surface. The metal endoprosthesis is separated, and its head and a plastic liner are removed. The wound cavity surface and the exposed surfaces of the disconnected metal endoprosthesis are washed, first, with 3% povidone-iodine solution using a pulse lavage system, then the wound cavity surface the exposed surfaces of the disconnected metal endoprosthesis are washed with 1% lavasept solution using ultrasonic lavage. The new endoprosthesis head and the new plastic liner of suitable size are placed in the metal endoprosthesis and the endoprosthesis integrity is restored. The wound cavity surface and the assembled metal endoprosthesis surface is washed with 1% lavasept solution using ultrasonic lavage. Gel with polyvalent Fagoderm bacteriophages is applied to the wound cavity surface and the assembled metal endoprosthesis surface, uniformly distributing it across the entire wound cavity surface and the assembled metal endoprosthesis surface, provding gel layer thickness of 1 to 3 mm. The wound is closed. Within 3-5 days of postoperative period, wound drainage is performed with 1% solution of Fagoderm bacteriophage upwards through the perforated drains.

EFFECT: method allows to save the prosthesis, reduce the risk of re-intervention in the affected joint, restore the functionality of the patient's limb.
